Paul Hembery: "With a notable lap time difference between the two compounds, strategy was at the forefront of this action-packed Indian Grand Prix. We saw some very different approaches being taken all the way down the grid, which was roughly split between drivers starting on the soft and the medium tyre. We also saw many teams split their strategies between both cars, in order to cover every possibility.
"Sebastian Vettel's early pit stop meant that he was able to undercut his direct rivals on the same strategy, but Webber was able to gain track position by staying out longer: which basically summed up how the different tactics worked. However, we are disappointed to see that some teams went against our recommendations and used the compounds for longer than we advised them to do.
"Most of all though, congratulations to Sebastian and Red Bull for their fourth consecutive double championship: a testament to their astounding capabilities in every area all year, including their skills at using the tyres and strategy to gain an advantage."
